ELECTRICALLY-HEATED CULINARY APPARATUS.

Specification of Letters Patent. Patented Dec. 26, 1916.

Application ledJune 25, 1910. Serial No. 568,871.

To (1f/Z whom '15 may concern.'

Be it known that l. WILLIAM S. llanaimr, Jr.. a citizen ot the United States, and a resident of llast Orange, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in tlectrieally-lleated Culinary Apparatus, of `which the following is a specilication.

My invention relates to electric resistance and heating devices znd particularly to such as are adapted for use with electrically heated vessels and other culinary apparatus.

The object ot my invention is to provide a specially simple electric heater ot' the class above indicated that shall be capable of continuous operation, either immersed in liquid or exposed-to the air,-Without appreciable deterioration. 1

Electric heaters and electrically heated chaling dishes and other vessels have been extensively used, lbut such apparatus has usually been specially constructed to embody the electric heater. V y my present invention, l provide a specially constructed electric heater whichl may be put to general use or be utilized with any of the usual forms of chatlng dishes and similar devices without i'iecessitating any structural change therein. lllhen used for heating liquid in a vessel, the fact that the heater element is entirely within, and not built. into .the walls of the vessel is of special advantage, since practically all of the generated` heat is available for useful work.

Figure 1 of the accompanying drawings is a partially `sectional elevation cfa chafing dish, or similar device provided with the heating device of my invention. Fig. 2 is a sectional view on a larger scale, and Fig. 3 of the heating device ot' Fig. 1; Fig. 4 is a sectional view, on a larger scale, ofthe handle ot the electric heating device which discloses a particularly advan'ftageous terminal arrangement. Fig. is a View, corresponding to Fig. l, of a modified heater structure .vhich' embodies iny inve.` tion. y

Referring to the drawings, the device here shown comprises ya hot water receptacle l, which is supported by, and may form a. part of, a stand comprising a ring feet 3 and handles l; an inner food receptacle 5, spacing ring 6, a lid 7 and an electric heatino device 8.

According to one formof` The device may be utilized in the usual manner without the electric heater, in which case, the ring 6 may be removed. The ring G is provided with a notch 9, as shown in Figs. 1 and 10 of the heater 8 projects.

The heating device 8 comprises a body member embodying 'a resistance element, and a handle member 10. The body member is constructed by welding two metal disks 11 together at their edges to inclose, the flat resistance element which comprises one or more' insulating disks 24 on which flattened helices of resistance ribbon are wound as shown in Fig. 3, the insulating disks being notched to hold the ribbons in position. Addition'al insulating disks 26 separate the helices from the metal disks and, when the body ot' the heating device is assembled, the parts'are all in intimate Contact.`

The handle member comprises a flattened metal tube which is welded to the body member and lthrough which the leads are threaded, and a hollow yh andle l()a which is mounted on the outer end ot' the tube to inclose the terminal members 12, 13 and 14.

The handle bar 10 constitutes a sheath for the resistance leads which extend into the hollow handle 1()a through a hole 15 in a screw-tlneaded enlargement 1G near outer end of the handle bar and areA severally secured to the' terminal members 12,13 and 14, being separated from each other by strips 17-ot' mica or other suitable `insulating material. The terminal mcn'ibers are secured to and are insulated from a projection 18 which extends from the handle bar into the hollow handle.

The hollow handlel()a is tapped at one end to engage the screw threaded enlargement 16 and is provided with a constrictcdV` opening 19 at the opposite end to receive circuit conductors Q0.

l. y arranging the terminal members 12,13 and 14 in the same straight line, the size of the handle may be materially reduced, while, at the same time, it is possible to secure a. certain amount of heat control, since an intermediate tap is brought out from the resistance.

In Fig. 5, the heater is shown in the form of a dish or pan 21, which ais-arranged the sides of are flaring and terminate in'a flange which extends between the outer and 2, through which the handle bar I the inner vessels of the device and renders the spacing ring 6 unnecessary. The dish or pan may be utilized as an electrically heated frying pan, stove or similar device, apart from the vesselsl and 5.

While I have illustrated my invention in connection with a single form of culinary apparatus, it is, of course, not restricted to any particular kind of apparatus, and I desire that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention:

l. An electric heating device comprising a body member, a set of supply conductors, a set of terminal conductors, an inclosing tube for the terminal conductors that terminates in a metal strip, aset of insulated binding posts secured to said strip in a longitudinal 4row and serving to connect the ends of the supply conductors at one side of saidstrip with the ends of the terminal conductors at the other side thereof, and a hol- ,ing posts serving to low handle removably secured to the outer end of the tube and inclosing the binding posts.

2. An electric heating device comprising a body member, a set of supply conductors, a metallic strip interposed between the said conductors, a set of binding posts secured to the said strip and insulated therefrom by means of insulating Washers, the said bindsupply conductors at one side ofthe said stri with the ends of the terminal conductors at the other side thereof, and a hollow handle surrounding the said binding posts and the said strip.

In testimony whereof, I-have hereunto subcribed my name this day of June, 191
